ERVIN G. BAILEY, OF NEWTON HIGHLANDS, Mz'xSSAC-HUSETTS, ASSIGNOBI TO BAILEY METER COM?AI'IY., k CORPORATION OF lvIASSACHUSETTS.

ILT'IEGRATOB.

T 0 all whom it mag/concern- Be it known that-I, ERVIN G.- BAILEY, a

citizen of the United States, residing in Newton -Highlands, in the county of .Middlese'x and State of Massachusetts, have invented an Improvem nt in Integrators, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

The present invention relates to an integrator of the kind used in connection with flow meters and the like, in which indicat ing orcounting mechanism is actuated by a. frictiovnally driven wheel, movable radially across the face of a revolving surface having radial components with which it is in contact.

The invention is embodied in an improved construction and arrangement of, the instrument, whereby there is a more eflicient contact between the wheel and the revolving surface than in instruments of the kind heretoforefused. It is practicable, moi-e overhtd utilize Ia'spring to vmaintain contin.uous ..cO. i :t,between the wheel and the rev'olvinglsurface, which contaet will not be broken byy'vibrationsas is possible in instruinents "where.gravity is relied on .to keep theparts', contact, and where the parts are so heavy as to have considerable inertia.

The ,construction embodying the invention admits of a simpler form of gearing than has been heretofore employed, so that less friction is encountered, greater accuracy is secured, and the instrument is less expensive to construct.

Figure It is a plan "iew of an integrator embodying the invention; Fig. 2 is a iaco view of the same; Fig. 3 is .a'face "iew of a ,srnodified form of traction wheel; and Fig. 4

is a .top edge view of said modified wheel, the position corresponding to that shown in Fig.

The integrator embodying the invention is provided with geared shafts 1. each having a hand 2 traveling over a dial 3 on a. face-plate 4 at the front of a frame 5 in.

-which' the gears are mounted, this part of the instrument constituting a counter train of ordinary construction. The frame 5 is shown as carried in an outer frame 6 mounted on a movable arm 8 actuated by meter, not herein shown, in the usual Associated with the integrator is a revoluble Specification of Letters Eatent.

Application filed April 19, 1915. Serial Ho. 22,298. it

make one revolution during a given period of time. In the construction shown, themain part of the arm 8 is behind the time disk as indicated in dotted lines, the counter frame being connected with the upwardly proyecting branch shown in front of the disk.

The counter train gears are driven, in accordance with the-invention, by a traction wheel. 10 mounted on a shaft 12, which has a bearing in the frame 5 andis nearlypen, pendicular to the face of the time, disk. The said shaft is so connected for operation with the counterframeas to hav'ea sufiicient endwisc movement with relation to the frame 5 as to admit of any endwise movement of the said shaft which may take place for any" reason such, for example, as vibration of the heavy parts. As herein shown the shaft 12 is connected with the gearing of the counterframe by means of a spur gear 13 which is of sufficient width to remain in mesh with the gearing of the train throughoutan'y in- ;dependent movement which can 'takeplace' The traction wheel 10 mounted onthe shaft.-

12 is neariy parallel to thefacetof the disk,

so thatthe side edge thereof makes contact with the disk and I have shown the Wheel as provided with-a flange,--.the' edgeof which constitutes the sideedge 'of'the wheel and lies in contact with the face of the disk, this. arrangcment resulting in a very effectual" vertimlls hung and therefore has no tenda which may arise from vibration of the parts,

or from other causes, do not affect the con tact which is maintained by the spring. It is, however, not essential to the invention that the integrator should be hung vcrtn cally, it being obvious that the instrument may be placed in any position with relation to the meter that may he found most convenient.

In the construction shown, the counter train is adjustable in its position with relation to the disk, in order that the traction wheel may lie in contact therewith in exactly the right position. For this purpose I have shown the frame as supported in the frame 6 by means of screws extending through the'frame 6 and engaging indentations in the ends-of the frame 5, the said said pin being provided with set nuts 19 (the front nut only being shown) between which the tongue 17 is held so that the said tongue can be moved in and out to a slight extent with relation to the frame 6 and locked in its adjusted position.

In the modification shown in Figs. 3 and f the traction wheel is provided with antifriction disks or rollers 20 having their axes in the plane of the traction wheel so that the friction encountered in the movement of the traction wheel across the face of the disk is minimized without lessening the frictional engagement between the -Wheel and the disk which produces the rotary movement 'of the Wheel in the travel of the disk.

lVhat I claim is:

1. An integrator comprising a clockdriven revoluble surface; a traction wheel in frictional contact with said surface, the planeof said wheel being nearly parallel to said surface; a spring constituting the sole means for holding said wheel in frictional contact with said surface; a meter adapted to move said Wheel radially with relation to said surface; and indicating mechanism operated by said wheel.

2. An integrator comprising a motor driven revoluble surface having radial components; a traction wheel, the side edge of which is in frictional contact with said surface, the axis of said wheel being nearlyperpendicular to the said surface; a spring bearing on the end of said axis and constituting the sole means for holding said wheel incontact with said surface; a meter adapt-- ed to move said Wheel radially with relation to said surface; and counting mechanism operated by said wheel. v

3. An integrator comprising a revoluble surface; a traction wheel adapted to lie in contact with said surfa e-and to be moved radially along said surface, said traction in. friction contact with said surface, theplane of said Wheel being nearly. parallel tosaid surface; a meter adaptedto movesaid wheel radially with relation to said surface; I-

indicating mechanism operated by said wheel; and means whereby said wheel is capable of movement lengthwise of its axes with relation to said indicating mechanism.

In testimony whereof, have signed my name to this specification in the presence of two subscribing witnesses.
